Abstract

fetched live from OpenAlex

The work presented in this paper uses speech analysis to detect candidates stress during HR (human resources) screening interviews. Machine learning is used to detect stress in speech, using the mean energy, the mean intensity and Mel-Frequency Cepstral Coefficients (MFCCs) as classification features. The datasets used to train and test the classification models are the Berlin Emotional Database (EmoDB), the Keio University Japanese Emotional Speech Database (KeioESD) and the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS). The best results were obtained with Neural Networks with accuracy scores for stress detection of 97.98% (EmoDB), 95.83% (KeioESD) and 89.16% (RAVDESS).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
